MACHINE FOR GIVING FORM TO MATERIALS..

SPECIFICATION forming part of Letters Iatent No. 630,265, dated August 1, 1899. Application tiled March 12, 1898. Serial No. 673,679. (No model.)

To @ZZ whom t may concern:

Beit known that I, JOSEPH I-IARMIsDAs PEL- LERIN, a citizen of the Dominion of Canada, residing at the city and district of Montreal, Province of Quebec, Oanada, have invented certain new and useful Improvements in Machines for Giving Form to Materials, (for which Letters Patent of the Dominion of Canada were granted April l, 1898, No. 59,476, the application forwhich was led September 3, 1897, Serial No. 78,678;) and I do hereby declare the following to be a full, clear, and exact description of the inventiomsuch 'as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for giving form to materials.

The object of my invention is to provide a device which will automatically clamp and shape the material operated upon to give it its desired form at a single operation.

A further object is to provide such device with means for shaping articles of various thicknesses and also provided with means for shaping the material into various forms.

To these ends my invention consists in the improved construction and combination of parts hereinafter fully described, and particularly pointed out in the appended claims.

In the drawings, in which similar letters of reference indicate similar parts in all of the views, Figure l is a side elevation of the matrix and platen of a press constructed in accordance with my invention. Fig. 2 is a sectional view of the same. Fig. 3 is an end view. Fig. 4. is a detail view of a modiiied form of block for supporting the heel-block.

My invention, as herein described, is intended more particularly for use in the shaping of sole-leather to form spring-heels,7 wherein the heel is formed integrally with the sole portion, but on a different plane.

A designates a matrix adapted to be secured in the stationary portion of a suitable press, said matrix having its upper portion o. concave or of the form to be given to the material operated upon. At the rear end of said ooncavity the matrix is formed with an anguiar face a. The rear end of the matrix is formed with a recess a2, within which is adapted to move vertically the block as, said block having a sliding connection with the matrix by means of the dovetail-slide d4 and depending bolts o5, adapted to slide in suitable openings ct. The bolts may be made adjustable, if desired, in order that the block di; may be limited in its movement. A suitable spring ci? serves to normally hold the block in its upper position.

Slidably mounted, as by the dovetail-slide as, on the block d3 is the heel-block a9, having its front edge beveled, as at ctw, to rest against the face a. A pin all, mounted in a suitable opening (L12, extending through the dovetail o8, serves to retain the heel-block in fixed position. The heel-block a9 is preferably made of different thicknesses to allow of a varying in the length of the inclined portion of the sole.

B designates a platen. adapted to be secured in the movable portion of a press, said platen being provided with a convex face I), adapted to lit the concave face a of the matrix. Adjustably mounted, as by a dovetail-slide b-, at the rear end of the platen is a block b2, having its front edge beveled, as at b3. The block b2 is adj ustable lengthwise to allow of the shaping of articles of various sizes. Slidably mounted, as by dovetail-slide b4, on the under side of the block b2 is a plate b5, having its front edge beveled to form a continnation of the beveled portion b3. A pin Us serves to retain the plate b5 in fixed position in a similar manner as the pin an.

By the construction shown it will be apparent that with the matrix and platen separated, as shown in Figs. l and 3, a downward movement of the platen will first clamp the material to be shaped by means of the plate b5 pressing the material against the heel-block a. A further downward movement of the platen causes the material to be drawn rearward a slight distance until the convex face of the platen reaches the upper face of the material, when the position of the material is :fixed and the further downward movement gives the material its desired form.

Material of various thickness can be shaped by moving the block b2 the required distance. The length of the inclined portion of the sole is regulated by the use of heel-blocks a9 and plates b5 of various thicknesses.

IOO

It will be apparent that by this construction I provide a simple and economical press which is simple in operation, durable in its construction, and which will shape the material in a perfect manner.

Having thus described my invention, what I claim as new isl. A pressing-machine having a portion of its matrix unyielding and a portion yielding, the distance between the yielding portion and the platen being normally less than the distance between the unyielding portion and said platen, in combination with an unyielding platen having a block adj ustably secured thereto over the yielding` portion of the matrix substantially as described.

2. A pressing-machine having a portion of its matrix unyielding, and a portion yielding, the top of the latter portion being provided with a removable plate whose surface is normally on a higher level than the top of the unyielding portion, in combination with an unyielding platen having a block adjustably secured thereto over the yielding portion of the matrix substantially as described.

3. `A pressing-machine, comprising a matrix; a block slidably mounted at the rear end thereof; a heelblock removably connected to said block; and means for normally holding said heel-block on a plane above the plane of said matrix; a platen adapted to contact with said matrix; a block adjustably connected to said platen at the rear end thereof and a plate removably connected to said platen-block, said plate and said heel-block forming the initial contact between said platen and said matrix.

4. The combination with a matrix, having a yielding block portion; of a heel-block, removably secured to said yielding portion.

5. A machine for shaping materials, comprising a matrix; a platen; and means for adjusting the thickness of the rear portion of said matrix and said platen, whereby the shape of said material may be varied.

6. A machine for shaping materials, comprising a matrix having a yielding portion; a platen; and means for varying the thickness of said yielding portion and the corresponding contacting portion of said platen.

7. A machine for shaping materials comprising a matrix; a platen; and blocks removably connected to said matrix and said platen, whereby the thickness of Va portion of said matrix and said platen may be adjustably varied.

In witness whereof I have hereunto set my hand in the presence of two witnesses. JOSEPH HARMISDAS IELLERIN.
